Metal Roof Over Garage ExtremelyWet Inside | Ask The Experts Forum

Guest User 12/27/2009	I've had a metal 3’ profile roof (18' x 10') fitted to our detached garage. The underside of the roof is extremely wet to the point it drips continuously. We have recently removed the eaves fillers to allow air in but this doesn’t seem to help much. We don’t have the option to lift the roof and insulate but could fit polystyrene underneath albeit not under the rafters. Will this stop the wetness?

Todd Miller Isaiah Industries, Inc. 12/28/2009	If you coul;d combine insulation with a vapor barrier (polyethylene) and still leave the vented airspace you should be okay.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14242/find/
Guest User 12/28/2009	Thanks, when you say "with a vapor barrier (polyethylene)" do you suggest something like a pond liner between the metal roof and the polystyrene?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14243/find/
